Note: The dot (1) on the piston skirt must point to the timing side to ensure that the notch (2) for the oil nozzle is at the correct position.

1. Displace the piston ring joints 120° to each other.
2. Coat all pistons and cylinder bores and the EN-50425 compressor with engine oil.
3. Turn the crankshaft to TDC of combustion stroke of cylinder 2.



4. Use the EN-50425 compressor (1) as shown in the illustration above.




Note: When using the old pistons, old connecting rods and old big-end bearing caps, install them at their original positions.

5. Install the 2 pistons with the connecting rod (1) and the connecting rod upper bearing shells (2) into cylinder 1 and 4.



6. Install the 2 big-end bearing caps (2) with the connecting rod lower bearing shells (1) to cylinder 1 and 4.

Note: Do not tighten the bearing cap retaining bolts (3).
